Rain water collection

GBA Editor | Posted in Green Building Techniques on


I live out on a small holding in South Africa. We have collected some rain water that flows directly from the gutter in 200-liter drums. We would like to increase the quantity captured. Can you advise where we could purchse these bags in South Africa with an outlet for easy access. I think they are a brilliant idea for storage and use.

Thus far we have used the water for irrigating indoor plants only, what are the chancers of using it for human consumption?

    The best way for you to find a local supplier of rainwater harvesting equipment is to inquire locally. You might begin by contacting contractors specializing in roof gutters.

    People have collected rainwater from roofs, stored it in cisterns, and used it for human consumption for thousands of years. To be sure the water is safe, however, precautions must be taken. Most systems include filters, and in some cases further treatment is advised.
